To ctZZ whom it may concern.-

Be it knownthat I,,WILLIAM L. KENDALL,

a citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented new and useful Improvements in Oar-Couplers, of which the following is a specification.

My invention relates to new and useful improvementsin car-couplers; and its object is to provide a device of this character which is constructed of a small number of parts, is durable, and is adapted to couple automatically.

The invention consists in providinga double draw-head,within one of the sides of which is pivoted a locking dog, which projects through the top of the draw-head and is connected to suitable operating mechanism located upon the car. The engaging end of said dog is concaved and is adapted to engage the toe of a coupling-bar similar to a bar which is located in the other side of said draw-head. This bar is supported at a point between its ends upon a fiat base which is formed within the draw-head, and the rear end thereof is enlarged or weighted, so as to cause the bar to balance on said base. The bar is held in position by a pin which extends through a slot, and the forward end of the bar is tapered and. provided with a toe which has a convex working face.

The invention also consists in the further novel construction and combination of parts Y hereinafter more fully described and claimed,

, nal section through said coupled draw-head.

Fig. 4 is a section on line 4 4, Fig. 3. Fig. 5

is a detail view of the coupling-bar, and Fig.

6 is a similar view of the locking-dog.

Referring to the figures by numerals of I reference, 1 is a draw-head having parallel recesses or passages 2 and 3, respectively, therein, and said draw-headis preferably cast in one piece of metal. A raised base portion 4 is formed upon the bottom of recess 2, ad-

' jacent to the front end thereof, while the botfront end, as shown at 5. An aperture 6 is provided within the top of recess 3, and a dog 7 is pivoted therein and provided with a rearwardly-extending arm 8, which is normally supported upon the draw-head and is connected, by means of a link 9, to an arm 10, which extends forward from a rod 11, revolubly mounted upon the end of a car 12. The lower or inner end of dog 7 projects rearwardly, and the end thereof is concaved, as shown at'l3.

Within the passage 2 and upon the raised base portion 4 therein is arranged a couplingbar 14, which projects beyond the end of the draw-head and is enlarged or weighted at its inner end 15. A slot 16 is formed in this rear portion of the bar, and a holding-pin 17 extends transversely through the draw-head and projects through this slot. The forward or outer end of the coupling-bar is tapered, as shown at 18, and provided upon its upper edge with a toe 19, the inner or working face of which is concaved, as shown at 20..

The coupling-bar 14 is held in a normally horizontal position upon the base 4, and when two draw-heads are brought together the tapered ends of the coupling-bars come into contact with the inclined bases 5 and are guided under the dogs 7. These dogs will he ends of the bars until the toes 19 pass thereunder. The dogs will then promptly swing the toes into position Within the concavities 13. The two draw-heads are thus securely locked together and cannot be disengaged until the dogs 7 therein are simultaneously raised by revolving the rods 11. The slots 16 within the coupling-bars permit said bars to swing vertically upon bases 4:, so as to be 1mafiected when the cars are traveling over rough tracks. Moreover, by employing the convex working face upon each dog which works upon a concave face the bars will continue to be securely held in position by the dogs when the cars are rounding a curve.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that tom of recess 3 is inclined upward from the w automatically swung upward by the tapered downward, so as to bring the convex faces of modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make'such changes as fairly fall within the scope of my invention.

Having thus described the invention, what is claimed as new is- 1. In a car-coupler, the combination with a draw-head having parallel recesses therein, an inclined base in one of said recesses, and a raised base in the other recess; of a dog pivoted within one of said recesses and above the inclined base, a concaved locking end to said dog, a coupling-bar supported upon the base within the other recess, a slotted and weighted inner end to said bar, a pin extending through the draw-head and the slot in the bar, a too at the outer end of the bar, and a convex working face therein.

2. In a car-coupler, the combination with a draw-head having parallel recesses therein provided with inclined and raised bases, respectively; of a dog pivoted within one of the recesses and extending therefrom, an arm to said dog normally supported upon the drawhead, a concaved end to the dog, a couplingbar supported upon the raised base within the other recess, a weighted and slotted inner end to said bar, a securing-pin within the draw-head and extending through said slot, a toe at the outer end of the bar, and a convex working face upon the toe.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM L. KENDALL.
